Influence of SNCR System on CFB Boiler Operation

doi:10.11930/j.issn.10.11930.2015.4.23

Abstract

Abstract: In this paper, the performance testing of a CFB boiler is introduced. And then through the testing, the impact of SNCR system on CFB boiler operation is analyzed. The results show that the deNOx efficiency of SNCR system can reach over 60%. High ammonia slip will accelerate the block of air preheater by fly ash. The interaction between the slipped ammonia and SO3 can cause fouling at the low-temperature end of the air preheater, which makes the resistance of the air preheater increase, but on the other hand it may lower the emission concentrations of ammonia slip and SO3.

Key words: thermal power plant, SNCR, CFB boiler, ammonia slip, deNOx efficiency
